HTTP Callout restriction doesn't allow Record-Triggered Flow to run on updates

Question

I'm running into a strange issue with my Record-Triggered Flow in Salesforce.

Basically, whenever a record is created or updated in Salesforce, we want to send a message to an external API. The problem is that only created records are running successfully in the Flow, updated records don't run. We see a message saying

The triggering record didn’t meet the condition requirements, so the flow didn’t run

There's a chain of issues resulting from using the HTTP Callout that led to this. The first is that they can't be under the Run Immediately path, otherwise we get this error.

A record-triggered flow can’t execute actions that make external callouts in a path that runs immediately.

So we created another scheduled path, with the Time Source being "When Record is Created or Updated" with the Time Source set to 0, so it will run immediately.

But this gives us another issue, in that the path requires Entry Conditions, we get this error if we try to set the Condition Requirements to "None":

This flow has a scheduled path with a time source based on when a record is created or updated. Configure the flow to run only when a record is updated to meet the condition requirements.

So we set up a Condition Requirement, something that would always be true, like "Id is not null", and set the Flow to run "Every time a record is updated and meets the condition requirements". But then we get this error trying to save it:

This flow has a scheduled path with a time source based on when a record is created or updated. Configure the flow to run only when a record is updated to meet the condition requirements.

Finally, we set the Flow to run "Only when a record is updated to meet the condition requirements".

But that leads us to our problem, in that the flow will only run if the Entry Conditions change from not meeting the requirements, to meeting the requirements. Ex: it will only run if the Id on the record changed from null to not null.

So updates aren't running because the Id field isn't changing. But due to the limitations of the HTTP Callout, I can't see any way around these restrictions to make the Flow run every single time. Is there a way around this? Or an Entry Condition I can set up that would fix this?

I think, I can solve your problem. Please check my suggestions.

This happen because HTTP Callout don't run immediately after db record / sales force doesn't allow that. So HTTP Callouts must run in asynchronous mode.
